The Powerball Jackpot has already risen significantly since this morning and is now reported as $350.1M Cash.

This suggests that the lottery expects to sell 392.7M for this drawing.

The Poisson distribution for numbers of winners at this sale level for randomized tickets is as follows:

 

k, number of winnersp(m,k)
034.50%
136.72%
219.53%
36.93%
41.84%
50.39%
60.07%
70.01%
